AUTOMOBILE TRANSMISSION.

Serial No. 512.503.

l linx invvnlion: Fig. 2

lt is oltl101nnlliplcdisk pnltcln. A disk (li-nm '15in lccyvd or olhfnwifm 80cm-vd lo the ontei rind of the motor shall, o1' lhv llywheel hub 1.1 which forms its cXtcnSion, und

set of friction rings 1G are keyed or sphned on the periphery thereof with a second set of disks 17 interposed alternatelywith them and keyed or splinedto the inner periphery of an inclosing drum 18. The latter has an elongated hub or tubular spindle 19 rotatable `on the motor-shaft eXtensio'n or hub 11. The drum acts as a thrust bearing and bymeans of suitably disposed fingers 20 pivoted on a plate 2l secured to the end of the transmission shaft or sleeve 12 that bear against Ystuds 22 on a push ring 41 which pass through the plate 21, and a clutch slide 23, the disks may be compressed and frictionally engaged so that .the transmission shaft and motor shaft are locked together. j

The change speed transmission between the shafts is preferably of the planetary type and may loe-of any desired construction. As herein indicated, the driving members of the mechanism are planetary pinions arranged in. sets upon studs 26.011 thel face of the fly wheel 10 to rotate therewith around the hub cally journaled upon the fly wheel'hub 1l, the Hy wheel in effect forming the rotor of the train. Obviously the arrangement and dimensions of these pinions and gears may be Varied or multiplied to give any desired change or relative speed. As herein indicated, a single reduction is obtained by pinions 27 on the studs meshing with a gear 2S whose extended hub 29 is rotatable on the sleeve 19 and carries at its outer end a drum 30 which may bei locked against rotation in the `usual manner as by a flexible encircling band 31. Intermediate pinions 32 are secured to rotate with the pinions 27 on the studs 26 in mesh with a gear 33 formed or secured on the inner end of the sleeve 19. Reversal of direction is obtained by suitably proportioned pinions 34 and secured to the pinions 27 to rotate therewith on the studs 26 in mesh with a reverse gear 35 concentrically journaled n the hub of the reduction gear. A drum 36 carried by the gear hub and conveniently adjacent to the drum 30 may be locked against rotation in the usual way as by a strap 37. A brake band 38 is applied to the drum 18.

As a further detail of construction7 a bearing 39 is provided for the sleeve coupled to the transmission shaft 7 on the outer end of a casing. or housing 40 which forms a combined crank and gear casing of the motor and the universal joints of the transmission shaft are beyond this bearing.

By this arrangement of parts, a veryflexible driving connection between the motor and drive shaft is obtained, which permits oscillation of the spring-supported frame on the axles without binding or otherwise impeding the mechanism, which gives the range of speeds and reversal of motion rej or arrangement of parts.

'tate in unison, change speed mechanism in mesh with sun gears concentri.

Ubviously changes in details and construction may be made without departing from the spirit of the invention and I do not care to limit myself to any. particular form `What I claim as my invention is 1. In an automobile, traction', bearing wheels, a frame yieldingly supported on the wheels, a motor on the frame, a main shaft in the motor, a transmission shaft journaled at its inner end on the outer end portion of the motor shaft, a clutch mounted on and supported wholly by the motor shaft for coupling it and the transmission shaft to romounted on and supported wholly by the motor main shaftand operatively connected to the transmission shaft, and operative connections between the traction bearing wheels and the outer end of the transmission shaft for driving the wheels.

2. In an automobile, traction bearing wheels, a frame yieldingly supported on the wheels, a motor supported on the frame, a main shaft on the motor, a fly wheel on the motor shaft, a transmission shaft rotatablymounted and supported at one end on the portion of the main shaft which extends beyond the ily wheel, a clutch mounted on and supported by the fly wheel and portions of theshafts for operatively connecting the main shaft and shaft to turn in unison, change speed mechanism mounted on the fly wheel and adjacent portion of the main shaft and connect- 105 ed to the transmission shaft to drive the lat ter from the main shaft, and operative connections .between the transmission shaft and the traction bearing wheels.

3. lin an automobile, wheels, a frame yieldingly-mounted-on the wheels, a motor mounted on the frame, a main shaft-on the motor havingv an `eXtension, a fly wheel on the main shaft, a transmission shaft journaled at extension of the motor shaft, a clutch mounted on the Hy wheel and adjacent portion of the transmission shaft for coupling the motor shaft and transmission shaft to rotate in unison, a change sneed mechanism 120 mountedion and supported wholly by the fly wheel and extension of the main shaft for driyu'ng thetransmission shaft from the main shaft, and operative connections between the transmission shaft and the trac-',125

tion bearing'wheels.

it. ln an automobile, a pair of traction bearing wheels, a frame yieldingly supported thereon, a motor mounted on the frame, a

main shaft in the motor, a ypwheel on the 180 the adjacent transmission traction bearing i one end on the main shaft, an extension on the main shaft wholly thereby and adapted to operate the -10 transmission shaft. Tn,testimony whereof I nflix my signature in presence of two witnesses.
